Supporting from behind rather than standing out in front is one skill President Bush's running mate is said to practice with great finesse.
"I worked with (Vice President Dick Cheney) when he was chief of staff and secretary of defense and know the extreme capability he has in providing high quality advice," said Roger Porter, a professor of business and government at Harvard University.
Cheney's solid influence has been visible during the past four years in the Bush White House. He has built a reputation of being one of the most active vice presidents in recent history.
Some pundits even say that Cheney, at times, has had more control of the White House from behind the scenes than Bush has demonstrated from the front lines.
"He has been given a broad range of responsibilities across the board and is intimately involved in implementing policies facing the executive branch," said Joel Goldstein, a professor of law at St. Louis University Law School. "Bush clearly relies on him."
During his years with the Bush administration, the things that have defined Cheney are his leadership of an administration energy task force and his efforts in making the case for war in Iraq, pundits say.
Goldstein said Cheney was the last person in the Bush administration to abandon claims of a link between Saddam Hussein and the Sept. 11, 2001, terrorist attacks. "The Iraq war bears his fingerprints," Goldstein said.
After attending Yale for six semesters, Cheney dropped out and returned to his home state to attend the University of Wyoming, where he received a master's degree in political science.
In 1964, he joined Richard Nixon's administration and in 1975 was appointed chief of staff in President Gerald Ford's White House.
